Abstract: A control entity (21) generates a set of control values for input to a processing entity (20) that needs these control values for its proper working. The control entity (21) can only generate the correct control values when enabled by an enabling entity (22), such as a smart card. The enabling and control entities (22, 21) each have a touch point word generator (26, 23) for respectively generating first and second identical successions of touch-point words (TPW(EE)i, TPW(CE)i). In addition, the enabling entity (22) has a build-word generator (27) for producing from each touch point word of the first succession, a corresponding build word (Ai) having a value dependent on the value of the touch-point word concerned and its order position (i) in the first succession. The enabling entity (22) passes these build words (Ai) to the control entity (21) where they are used together with the corresponding touch point words (TPW(CE)i) of the second succession, to produce a series of command word values serving as the required control values. As the build words are of different values and are needed to generate the correct control values, it is difficult for an attacker to modify the control entity (21) in a way avoiding the need for the enabling entity (22) to be present.

Abstract translation: 控制实体（21）生成一组控制值，用于输入到需要这些控制值用于其正常工作的处理实体（20）。 控制实体（21）只有在诸如智能卡之类的启用实体（22）启用时才能产生正确的控制值。 启用和控制实体（22,21）各自具有用于分别产生第一和第二相同序列的触摸点词（TPW（EE）i，TPW（CE）i）的触摸点词生成器（26,23）。 另外，启用实体（22）具有构建字生成器（27），用于从第一序列的每个触摸点字生成具有取决于触摸点字的值的值的对应构建字（Ai） 关注及其秩序状况（一）。 启用实体（22）将这些构建单词（Ai）传递到控制实体（21），其中它们与第二次相继的对应的触摸点词（TPW（CE）i）一起使用），以产生一系列命令字 作为所需控制值的值。 由于构建单词具有不同的值并且是生成正确的控制值所必需的，所以攻击者难以以避免使能实体（22）存在的需要来修改控制实体（21）。

Abstract: Data are transmitted in blocks over a channel together with control signals for coordinating access to the channel. The control signals have the same values as some of the data blocks, these values being selected so that the control signals are spaced throughout the population of data block values and so that there is a greater Hamming distance between the control signal values than between the data signals. The control signals are transmitted between delimiter signals which differ from any of the data block signals, and are passed through a scrambling and encoding system in the same way as data signals, so that the spectrum of radiated electromagnetic emissions from the channel is not affected by the control signals.

Abstract translation: 通过信道以块的方式传输数据，以及用于协调对信道的访问的控制信号。 控制信号具有与一些数据块相同的值，这些值被选择，使得控制信号在数据块值的整个数据间隔开，并且使得控制信号值之间的汉明距离比数据之间要高 信号。 控制信号在与任何数据块信号不同的定界符信号之间传输，并以与数据信号相同的方式通过加扰和编码系统，使得来自信道的辐射电磁辐射的频谱不受 控制信号。

Abstract: A communication device (60) for simultaneously transmitting information (76, 78) on multiple sub-channels encodes information (75) for each of the multiple sub-channels with a coding scheme to produce channel encoded information. A mask vector (72), derived from a redundancy in the coding scheme, encodes (68) the channel encoded information (75) to transform the channel encoded information into codewords having pairwise Euclidean distance properties identical to those of the channel encoded information (75). Modulation of the sub-channels in accordance with the codewords in a modulator then produces a composite signal envelope (78), shown in the figure, having a peak-to-mean envelope power ratio (PMEPR) reduced relative to a PMEPR for correspondingly modulated channel encoded information.

Abstract: Authentication by an intermediary F (e.g. a bank) of an originator C of a message (e.g. a client sending an instruction to pay a merchant M) is accomplished using a protocol which does not require the intermediary to possess passwords used by the originator C and the merchant M to protect the contents of the message. Furthermore, the protocol does not require any party to the transaction to decrypt any value previously encrypted by any other party, so a reversible encryption algorithm is not required.

Abstract translation: 消息发起方C（例如，发送支付商户M的指令的客户端）的中介人F（例如银行）进行的认证是使用不要求中介者拥有发起方C使用的密码的协议来实现的，并且 商家M保护消息的内容。 此外，协议不要求交易的任何一方解密任何其他方以前加密的任何值，因此不需要可逆加密算法。

Abstract: Described herein is a printer having a printhead (102) which traverses laterally across a sheetlike print medium (110) and which thereby defines a laterally-extending print zone across the print medium. A paper transport mechanism in the printer has drive rollers (114) and associated pinch wheels (180) to drive the print medium through the printer's print zone. The paper transport mechanism further includes an upper print media guide (202) and a lower print medium guide (126). The two print medium guides are shaped at their transverse ends to bow the transverse edges of the print medium downwardly to reduce its tendency to buckle upwardly into the printhead. In order to fit the upper print medium guide into the limited available space above the drive rollers, it is made of a lower molded portion (170) for paper contact and an upper backing portion (172) for rigidity. A pinch finger (191) extends toward the printer's print zone beyond the pinch wheels to establish a pinch point (192) against the drive roller in near proximity to the print zone. To facilitate ejection of printed pages, the upper print medium guide is formed with a series of ribs (204) which contact the paper. The ribs reduce friction and static buildup, and make it easier to push the paper from the paper transport mechanism.

Abstract translation: 这里描述的是具有打印头（102）的打印机，该打印头横向穿过片状的打印介质（110），从而限定穿过打印介质的横向延伸的打印区域。 打印机中的纸张传送机构具有驱动辊（114）和相关联的夹紧轮（180），以通过打印机的打印区驱动打印介质。 纸张传送机构还包括上打印介质引导件（202）和下打印介质引导件（126）。 两个打印介质引导件在其横向端部成形，以向下弯曲打印介质的横向边缘，以减少其向上压入打印头的趋势。 为了将上部打印介质引导件装配到驱动辊上方的有限可用空间中，它由用于纸张接触的下部模制部分（170）和用于刚性的上部背衬部分（172）制成。 挤压手指（191）朝向打印机的打印区域延伸超过夹紧轮以在靠近打印区域的位置建立抵靠驱动辊的夹点（192）。 为了便于打印页的排出，上部打印介质引导件形成有一系列与纸接触的肋（204）。 这些肋骨减少了摩擦和静电积累，并且使纸张从纸张传送机构更容易地推动。

Abstract: Through holes (2) are bored in given positions of a disc enclosure (101), and sealing members (1) having threaded holes (6) in which screw members (3) for fixing external components can be driven are provided. The through holes (2) are sealed by the sealing members (1), and a printed circuit board (116) and other external components are mounted on the outer surface of the disc enclosure (101) by screwing the screw members (3) into the threaded holes (6). Thus, it is possible to prevent dust particles from entering the interior of the disc enclosure, the external components can be fixed to the disc enclosure (101) easily without increasing the manufacturing cost due to the increased number of machining steps, and without causing the device to be larger.

Abstract: To facilitate the carrying out of a range of different types of management task in a computer system (such as fault diagnosis and service installation), declarative models (22) are constructed of the various services provided by the system (10-13). These models (22) specify the requirements that need to be met for the corresponding service to be available. These requirements are set out in terms of the system entities that need to be present and the inter-relationships of these entities. In addition, each management task is specified in a corresponding task program (21) in terms of general inferencing operations that can be performed on any of the models. Execution of a particular management task involves carrying out inferencing operations on the appropriate service model (22) in accordance with the task program (21) for the management task under consideration.
